My invention refers to hammers for securing standard fiber carpet Strips to be nailed to the edges of cement or other terrazzo floors, the said strips being fitted to the meeting edges of floors and washboard.

The object of my invention is to provide a barrel for the reception of an oscillatory hammer head, the bottom seating face or the barrel being provided with a channel for encasing a strip, having groups of pins and securing nails, which strip serves as a carpet attaching means. Hence, the securing nails carried by the strip may be driven into a cement floor by the hammer head without mashing down or engaging the strip pins, whereby they are maintained in their standard inclination for receiving the edge of a carpet.

A further object of my invention is to provide the barrel with a handle having a spring connection with said barrel, whereby vibration is absorbed when the hammer head is subjected to blows in driving the securing nails, whereby said strip is fastened to the floor.

It is understood, however, that the device may also be used in connection with securing the strips to wood or other floors.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the novel construction, combination and arrangement 01. parts, substantially as hereinafter described, and more particularly defined by the appended claim, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claim.

In the accompanying drawings is illustrated one complete example of the physical embodiment of the present invention constructed according to the best mode so far devised for the practical application of the principles thereof.

In the drawings:

Figure 1 represents a side elevation of a ham-' mer embodying the features of my invention, fitted to the corner of a washboard and floor, the same being in section as indicated by line I, l of Figure 2.

Figure 2 is a plan sectional view of the same, the section being indicated by line 2, 2 of Figure 1.

Figure 3 is another plan sectional View of the same, the section being taken upon a lower plain as indicated by line 3, 3 of Figure 1.

Figure 4 is a longitudinal sectional elevation of the hammer and associated parts, the section being indicated by line 4, 4 of Figure 1; and

Figure 5 is a cross sectional view of the meeting corner between a washboard and floor show- 1 Claim. (01.145-46) z ing the carpet and pad fitted to the pin carrying strip.

Referring by characters to the drawing, A indicates a washboard and B a terrazzo floor composed of cement or other waterproof material.

Fitted to the corner intersecting the floor and washboard is a thin narrow fiber strip I of standard type, having angularly upstanding groups of pins 3, which pins project above the strip and are inclined towards the washboard A, it being understood that the pins are in the form of standard tacks extending up through the strip and that groups of the same are staggered with relation to each other, as best indicated in Figure 3 of the drawings.

Spaced at suitable intervals apart are strip securing or floor nails 4, the points of which are embedded into said strips prior to being forced therethrough and into the fioor, whereby the strips are anchored in their corner position.

As best shown in Figures 1 and 4 of the drawings, when one of these nails 4 are to be driven home, a hammer is utilized, embodying the features of my invention.

The hammer comprises a tubular barrel 5, the bottom seating face of which is formed with an annular channel 6 surrounding the tubular bore of the barrel, whereby upon setting the lower rim 6' of the hammerupon the strip it encases a group of the pins 3 which are positioned about the nail 4 to be operated upon, which nail when the barrel is fitted to the washboard is positioned approximately central of the tubular barrel bore, whereby irrespective of the position of the nail 4 its head will always be within the area of said bore while the pins 3 will be within the channel 6.

Reciprocatively mounted in the tubular barre] 5 is a hammer head I. The hammer head is provided with a longitudinal groove 8 and fitted into this groove is a projection, preferably in the form of an antifriction ball 9, which ball is revolvably seated in a threaded aperture that is formed in the upper end of the barrel and said aperture carries a screw threaded plug I0 for engaging and confining the ball 9. Thus, it will be noted that reciprocative movement of the hammer head is limited, whereby said head is at all times held within the tubular barrel, irrespective of the position of the hammer as a whole.

In order to properly manipulate the hammer, I provide a handle H, which handle is flexibly secured to the barrel by studs H, H", which latter stud extends from said barrel.

These abutting studs are encased in a stiff coil spring I2, the ends of which are welded or 3 otherwise secured to the barrel about its stud and to a shoulder of the handle II. By this flexible connection, when the hammer head receives blows for driving the nails vibration from the same is absorbed by the yieldable spring connection between the barrel and handle.

From the foregoing description, it is apparent after the hammer is properly positioned, the bottom face of its hammer head will engage a nail and thereafter by a few sharp blows the nail 4 will pass through the strip and its pointed end will be embedded into the surface of the floor to thus attach the strip throughout its length.

Thereafter, as best shown in Figure 5 of the drawings, a floor covering is completed by first laying down a pad C followed by laying the car pet D, whereby its corner edges are securely anchored by engagement of said edges with the various groups of strip pins 3, the pointed end of which are of such length that they would not pass through the thickness of the carpet.

While I have illustrated one exemplification of my invention and my nucleus of details, it is understood that I may vary the details within the scope of the appending claim.

I claim:

In a hammer for securing carpet anchor strips to floors, having groups of carpet attaching pins extending upwardly therefrom; a hammer comprising a tubular barrel having a seating bottom, provided with an annular channel, adapted to encase and protect a group of exposed carpet attaching pins, having floor nails nested within the groups, a longitudinally disposed grooved hammer head, reciprocatively mounted in the barrel, a projection carried by the barrel and engagin the hammer head groove, and a handle extending from said barrel having a resilient connection between the handle and barrel, whereby blows upon said hammer head for driving the floor nails into a floor protect strip pins nested in the channel.
